Wide binaries without viable bound Newtonian orbits
L. Pasquini, R. Saglia, F. Patat +7
Context. Wide binaries offer a unique opportunity to test gravity in the low acceleration regime, where deviations from Newtonian dynamics may appear. Aims. We use high-resolution…
Testing gravity with wide binaries -- 3D velocities and distances of wide binaries from Gaia and HARPS
R. Saglia, L. Pasquini, F. Patat +5
Wide Binaries (WBs) are interesting systems to test Newton-Einstein gravity in low potentials. The basic concept is to verify whether the difference in velocity between the WB comp…
Masses of the Hyades white dwarfs: A gravitational redshift measurement
L. Pasquini, A. F. Pala, H. -G. Ludwig +3
Context. It is possible to accurately measure the masses of the white dwarfs (WDs) in the Hyades cluster using gravitational redshift, because the radial velocity of the stars can…
Tachoastrometry: astrometry with radial velocities
L. Pasquini, C. Cortés, M. Lombardi +3
Spectra of composite systems (e.g., spectroscopic binaries) contain spatial information that can be retrieved by measuring the radial velocities (i.e., Doppler shifts) of the compo…
Optical Identification of ROSAT sources in M 67: activity in an old cluster
L. Pasquini, T. Belloni
We present optical identification and high-resolution spectroscopy of ROSAT sources in the field of the old open cluster M 67. For the first time it is possible to analyze coronal…
